MY FS FLIGHTS
Flight Score
Arrival
Fly a steeper descent on final so you cross the threshold at 50 ft agl instead of 148 ft agl.
What happened: The aircraft crossed the threshold at 148 ft agl against a 50 ft agl target, well above the normal profile. The touchdown point was also long at 3,361 ft against a 1,500 ft target, a pattern often seen after high threshold crossings.
Watch for: Radio altimeter against the 50 ft threshold crossing target on short final.
Even a modest height error carries straight through to the touchdown. Geometry alone says that crossing the threshold 10 feet high on a 3° path moves your touchdown roughly 190 feet further down the runway before the flare adds anything.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
Two stabilised approach gates, each with six checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.
The approach, gate by gate
Side view — the last 5,089 ft of the approach.
Plan view — the first 5,089 ft of the 11,947 ft runway, to the same scale as the side view.
Touched down 3,361 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Cessna 750 Citation X taxied from the parking area to runway 08L at LFPG Charles de Gaulle International Airport in 18 minutes, covering a distance of 10 nm.
The aircraft commenced its departure roll on runway 08L, using 3,626 ft of runway (26 % of the available length) and lifted off at 133 kt. Local conditions were 56 °F with a wind from 040° at 3 kt, including a 2-kt headwind and a 2-kt crosswind.
Climb began one mile north of Mitry-Mory, with the airplane ascending from 857 ft asl to 21,608 ft asl, a gain of 20,751 ft achieved in 7 minutes while covering 40 nm.
The first cruise segment started overhead Wacquemoulin, lasting 2 minutes and extending 12 nm at level flight.
A second climb segment was recorded overhead Quiry-le-Sec, where altitude increased from 21,840 ft asl to 24,695 ft asl, a rise of 2,856 ft in 2 minutes over 11 nm.
The next cruise phase commenced one mile west of Prouzel and continued for 3 minutes, covering 21 nm at cruise altitude.
Descent commenced over Moyenneville, with the aircraft descending from 24,097 ft asl to 23,573 ft asl, a loss of 524 ft in 2 minutes while traveling 8 nm.
Climb resumed over Le Crotoy, raising the airplane from 23,589 ft asl to 24,167 ft asl, an increase of 578 ft in 2 minutes across 8 nm.
A further cruise segment began one mile west of Fort-Mahon-Plage, lasting 2 minutes and covering 10 nm.
Climb continued eight miles west of Le Touquet-Paris-Plage, with altitude climbing from 23,884 ft asl to 24,569 ft asl, a gain of 685 ft in 2 minutes over 10 nm.
Descent started 15 miles west of Equihen-Plage, dropping from 24,603 ft asl to 3,206 ft asl, a decrease of 21,397 ft in 12 minutes while covering 58 nm.
The aircraft then cruised level overhead Cudham for 10 minutes, traversing 26 nm.
A final descent segment began over Brixton Hill, with altitude falling from 2,860 ft asl to 953 ft asl, a loss of 1,907 ft in 4 minutes and a distance of 10 nm.
During the final approach to runway 27L at EGLL London Heathrow Airport, the airplane descended from 801 ft agl to 115 ft agl in 113 seconds and was scored on the stabilisation gates.
Landing on runway 27L was executed with a threshold height at 148 ft agl noted as excessively over target, while the threshold speed was 122 kt. Touchdown occurred 1,786 ft beyond the touchdown zone at 109 kt, with a hard touchdown rate of minus 408 fpm and a lateral deviation of 20 ft from the centreline. Local weather was 52 °F with a wind from 099° at 3 kt, including a 1-kt crosswind and a 3-kt tailwind. Total landing distance measured 4,614 ft, representing 39 % of the runway length.
Runway rollout alignment was reported as very good.
The aircraft taxied from the runway to the parking area in 4 minutes, covering less than 1 nm.
In total, the flight covered 232 nm, required 62 minutes of airborne time, and consumed 1,506 lb of fuel.
The approach to runway 27L at EGLL was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope, centreline and speed all within limits. The aircraft descended from 801 ft agl to 115 ft agl in 113 seconds on the final approach.
At the threshold the aircraft was at 148 ft agl, which was excessively over the target height, while the threshold speed of 122 kt was recorded as good.
Touchdown occurred 1,786 ft beyond the touchdown zone with a speed of 109 kt that was judged good, but the touchdown rate was hard at -408 fpm and the touchdown point was slightly misaligned by 20 ft from the centreline.
The total landing distance was 4,614 ft, representing 39 % of the runway length, and the runway rollout alignment was very good.
To refine the performance, reduce the descent rate near the threshold to achieve the intended height and adjust the flare timing to obtain a softer touchdown, which will also bring the touchdown point closer to the intended zone. Maintaining the current alignment and speed control will preserve the strong rollout results reflected in the score of 81.8 %.
